Now she has announced the release of her two books, titled ‘In The Shadows of The Duchess’ parts one and two, writing on her private Twitter account that she “couldn’t help but let it slip”.

“There are actually two books coming out,” she tweeted.

Originally the book was to be titled The Diary of Princess Pushy’s Sister, then was later renamed A Tale of Two Sisters, but appears to have gone through another round of rebranding.

The tweet was accompanied by the hashtags “#April” and “#June”, implying that the books will be released right as Meghan is due to deliver her first child, prompting some royal fans to speculate that Samantha is trying to cash in on the media attention that will be on the Duchess of Sussex at the time.

It’s well known Samantha, 54, didn’t grow up with her royal half-sister and has been estranged from her since Meghan cut ties with much of the Markle family following the drama surrounding her May 2018 wedding.

Of course, Samantha’s regular media outbursts don’t help her case, and her book announcement comes just weeks after she was placed on a “fixated persons list” by the royal family’s security, singling her out as posing a major “reputational risk” to the royal family.
